Xia Yuan-f

Abstract

Gold occurs mainly in mineral state. Only a small amount is in fine-grained dispersed phase. Gold-Carrying minerals are mainly chalcopyrite, arsenopyrite, pyrite, gangue, pyrrhotite and so on. Gold minerals are mainly Gold, silver-gold, the fineness averaging 745.57. Gold is embedded as inter-crystal, inclusion and fissure-filling form. Gold is uneven distributed in ores and orebodies.
